SERVICE AND REPAIR

4.1 Preparing the Range for Servicing

For most servicing of this appliance (for example, involving
disassembly, or component removal / installation), you will need to do
the following prior to starting:
■ Turn off the gas supply to the range by closing the gas valve at
the wall
■ Turn off the electrical power to the range by removing the power
cord from the electrical outlet, and putting the circuit breaker in the
OFF position (or removing the fuse)
■ Make sure the range is not hot
■ Wear protective clothes: long sleeves, gloves, safety glasses
If testing the appliance requires the use of electrical power and/or an
open gas supply, exercise extreme caution.
